zephyr board definitions, drivers, and shell for coquette

revisions

• coquette@mariposa is the final butterfly body board design - this doesn't cover the two prototypes, those may be added later to support our prototype versions
• coquette@nightingale is the rounded bird-body board design that replaces mariposa

shell

yes there's a shell

i'm just starting work on this, the readme is also my notes

shell commands to test

enable device:

i2c write_byte i2c1 0x2c 0x0 0x1

disable device:

i2c write_byte i2c1 0x2c 0x0 0x0

check engine status:

i2c read_byte i2c1 0x2c 0x40

reset undervoltage lockout/por:

i2c write_byte i2c1 0x2c 0x13 0x1

reset thermal shutdown:

i2c write_byte i2c1 0x2c 0x13 0x2

max current 25.5mA (should be default, do not set 51mA!):

i2c write_byte i2c1 0x2c 0x1 0x0

set dot current for all four channels to 18mA:

i2c write_byte i2c1 0x2c 0x14 0xb5
i2c write_byte i2c1 0x2c 0x15 0xb5
i2c write_byte i2c1 0x2c 0x16 0xb5
i2c write_byte i2c1 0x2c 0x17 0xb5

enable all four leds:

i2c write_byte i2c1 0x2c 0x02 0x0f

set all four channels to exponential pwm with animation disabled:

i2c write_byte i2c1 0x2c 0x04 0xf0

save config:

i2c write_byte i2c1 0x2c 0x0f 0x55

set LEDs to 100% of configured current (18mA with settings above):

i2c write_byte i2c1 0x2c 0x18 0xff
i2c write_byte i2c1 0x2c 0x19 0xff
i2c write_byte i2c1 0x2c 0x1a 0xff
i2c write_byte i2c1 0x2c 0x1b 0xff
